Abstract: In homotopy theory, we don't need infinite spaces. This is an overstatement, but topological spaces with a finite number of points are richer than one might think, even though they are a bit
unintuitive at first glance. After a somewhat gentle introduction to how they behave, I will explain the link they have with posets and talk about a particularly interesting result regarding the homotopy theory of
finite spaces."
